In a cramped, dimly lit room, a Japanese amateur takes matters into his own hands, literally. With a week's worth of pent-up semen ready to burst, he eagerly grabs his favorite masturbation sleeve. His hand moves rapidly up and down his throbbing shaft, the tight friction driving him wild. His body convulses as he reaches his peak, and with a guttural groan, he releases, shooting his load twice in quick succession, leaving him breathless and spent.
